the amount of strain energy stored (absorbed) in a material when loaded (without permanently deforming) to its elastic limit; it is determined by measuring the area under the stress-strain curve up to elastic limit (see: strain energy; resilience), materjali elastsuspiirini koormamisel absorbeerunud (salvestunud) deformatsioonienergia; on mõõdetav tõmbediagrammi aluse pindalaga koormamisel elastsuspiirini (vt deformatsioonienergia; resilientsus/nõtkus)
